Go - The Complete Guide

Maximilian Schwarzmüller connects Go fundamentals with several projects and a larger REST API using authentication and a SQL database. It suits programmers new to Go who want to follow the language into an application. The API project is a learning context; independent testing and security review are needed before adapting it for real users.

What you will learn

• Use functions, pointers and collections.
• Explore goroutines and channels.
• Build an API with authentication and SQL.

Who this suits

Basic experience with any programming language is strongly recommended; no previous Go knowledge is assumed.

Before you enroll

Check the Go and dependency versions used in each example. Write and run your own tests, including invalid inputs and failure paths. Hosting, databases and cloud services may require separate accounts or fees. A working course project still needs independent security and operational review before real users depend on it.

Udemy offers paid purchase or subscription access depending on the current course and region. Paid teaching courses provide completion certificates under Udemy’s policy. Check current access terms and any separate software or material costs before enrolling.

Put it into practice

Add a new endpoint to a local practice API and test a valid request, a missing record and an unauthorized request.
